' Patented sept. 2, 1919.

Application filed April 29, 1916. Serial No. 94,497.

To all 'whom t may concern:

4Be it -known that I, ERNEST D. ANDERSON, a citizen of the UnitedStates, and resident of Long Beach, in the county of Nassau and iStateof New York, have invented certain new and useful Improvements in CanForming and Heading Machines, of which the following is a specification.I

An object of my invention is to provide a machine for automaticallyforming can bodies, applying heads upon such can bodies, and for seamingsaid heads upon the endsof the bodies in a continuous or successivemanner.

Another object of my invention is to provide -pneumatically controlledmeans for seaming heads or closures on can bodies, a further objectbeing to cause such means to rotate around the can body and the headapplied thereto, for seaming the head and body together, in a continuousmanner.

A further object of my invention is to provide means for automaticallybeading the end portions of the bodies opposite the head appliedthereon, and 4delivering the headed and beaded bodies from the machine.

Other objects of my invention, as well as novel details of improvementand combinations of parts, will be more fully hereinafter set forth andthen pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

Similar numerals and letters of reference indicate corresponding partsin the several views.

In the accompanying drawings the numeral 1 indicates a suitable frameadapted to support mechanism hereinafter explained. In the exampleillustrated, the frame 1 is equipped with a rotative device which Iterm, generally, a turret indicated at A, and with a substantiallysimilar turret B, said turrets being suitably spaced apart. The turret Ais provided with receivers for can bodies, that are adapted tosuccessively receive can bodies from a can-body forming machine, or fromany other desired source of supply, and while retaining thev bodiesthereon to present the bodies in different positions for differentoperations, such as for straightening the bodies, applying headsthereto, seaming the heads on the bodies, and delivering the headedbodies from said receivers. Where the can bodies are to be beadedadjacent to their ends opposite the heads, the turret B is utilized, andas illustrated, is provided with means for taking the headed can-bodiesfrom turret A and presenting them to devices for performing certainoperations thereon, such as for forming the beads adjacent to the openends of the can bodies, pressing the longitudinal seams of the bodies atthe beads, and discharging the headed and beaded bodies.

Referring now more particularly to the turret A, and the devicescoperative therewith for applying and seaming heads on the can bodies,it will be understood that the turret comprises various coperative partswhich may be described as follows: A vertically disposed shaft 2 issuitably journaled in bearings in the bed plate of frame 1, and saidshaft is shown provided with a bushing or the like 3, shown resting uponframe 1 and secured thereto (Figs. 6 and 20) upon whiclrbushing rests aturret plate 4 centrally disposed upon said shaft and suitably securedthereto, as by a key. Turret plate 4 is provided with a suitable numberof radially disposed grooves or channels 5 (Figs. 20 and 21), inwhiclrslides 6 are disposed so as to slide radially. The slides 6 areprovided with receivers 7 for can-bodies b, which receiversare shownprovided with longitudinal grooves at 8 to receive the can-body seams.and at 9 the receivers are provided with can-body retainers, adapted toenter the bodies to retain them on the receivers 7 (Fig. 3). Theretainers 9 are 'shown loosely mounted on the receivers 7 and held inplace by pins 10 entering slots 11 in said receivers, springs 12 betweenreceivers 7 and retainers 9 serving normally to press the latteroutwardly. The outer ends of the receivers 7 and of the retainers 9 areshown beveled or tapered for ready entrance into can bodies. Thereceivers 7 have abutments or stops at 13 against which the ends of thecan bodies must abut for centering the bodies on the receivers andresisting end thrust of the bodies. While the receivers may be formeddirectly on the ends of the slides 6, said receivers are preferably madeseparate therefrom to fit u on projections 6n at the outer ends of the sides, clamping means, such as screws 14, (Figs. 2, 3) serving tosecurely hold the receivers 7 on the slides. The outer ends of thereceivers 7 are shown provided with recesses 15. A plate 16 secured uponplate 4, retains the slides 6 properly in the grooves or channels 5,(Fig. 20). Plate 16 is retained on plate 4 by means of screws. Plates 4and 16 are comprised in the turret, and the latter is -held on shaft 2by nut 17 receiving threadsl upon the end of shaft 2 and bearing againstan interposed washer or the like 18 (Fig. 20).

The slide-carrying plate 4 is to be rotated step by step, and each timesaid plate stops a can body may be placed upon one of the receivers 7. Ihave illustrated means to automatically feed can bodies to theappropriate body-receiver 7 the discharge end of said delivery meansbeing indicated at 19 in Fig. 1. The means illustrated for deliveringcan-bodies to receivers 7 will be more fully hereinafter described.

Any suitable means may be provided for rotating the slide-carrying plate4 step by step. For such purpose I have illustrated tempo@ a Genevamovement comprising an escapement Wheel or plate having radial grooves2l corresponding in position to the slides o, and secured upon shaft 2(Figs. 6 and 26). An arm 22 having a projection or roller at 23 to entergrooves 21 rotates escapement,

wheelv 20 in an ordinary manner. Arm 22 is secured upon a shaft 24carried in suitable bearings on frame 1, and shown provided with a bevelgear 25 meshing with a bevel gear 26 on a drive shaft 27 journaled insuitable bearings on frame 1, (Fig. 6). Shaft 26 may be driven in anysuitable manner, such as by a sprocket wheel 28 secured thereon,receiving a chain 28a from any suitable source of power, such as fromthe can-body forming machine as hereinafter explained. Each time wheel20 is moved a step a-can body receiver 7 will be brought to rest inposition to receive a can body from the delivering part 19.

In order to properly seat can bodies on receivers 7, and to straightenthe edges of the can bodies with respect to their seams, I preferablycause the can bodies to be brought at their first stopping pointopposite an abutment 30 secured on frame 1, and having a suitablesurface to receive the outer ends of the can bodies, (Fig. 1). rlheabutment 30 is preferably provided with a pin or project-ion 31 to enterthe recesses 15 of receiver 7 to cause the latter to be properlycentered when the receivers with the can bodies are successively pushedtoward said abutment (Fig. 1), as will be presently explained. At thenext step, each can body is. brou ht to rest in position with respect tomeans or applying heads a upon the bodies l) (Figs. 1, e1, se and. es).trated of the class having the depressed ortion a adapted to enter thecan body at its end,'while the flange a2 of the head projects Voutwardlyto be seamed over theed e of the can body (Figs. 31, 34 and 3LP). n theexample illustrated a suitable magazine Ifor heads a is illustrated at32, carried by a standardla on frame 1, adapted .to receiveaasuitable'stack ofjheads a (Figs. 1, 6 and 31), fin ers at 33,pivotally supported upon standar 1,, engaging the lowermost head of thestack, springs 34 coperating with said fingers and the magazine servingnormally to retain the fingers closed with respect to theheads forsupporting the latter. Beneath the magazine 3-2 1 have shown means for'taking ofi' the lowermost head a ofthe stack and presenting it oppositethe n can body on the opposing. or adjacent body 'receiver 7, thearrangement shown for such purpose being as follows: A rocking arm 35 isshown carried by a shaft 36' journaled in bearings upon standard' 1a(Figs. 31 and 33), and said arm 35 is shown provided with' a hollow orrecessedfportion which recelves s a polygonal block 37 through which ashaft The heads a are illus- Ito receive a can bo 36 asses. A spring 38interposed between sai block and the outer end of arm 35 normally tendst0 move said arm toward the left in Fig. 31. At the outer end of saidarm is pivotally supported a head 39 recessed at its Aouter end andadapted to enter the recess of the can heads a. Head 39 is shownpivotally supported upon a shaft or pin 40 carried by arm 35, a spring41, interposed between arm 35 and head 39, normally tending to push saidhead forwardly-v to a tilted p0- sition to resiliently engage can heads,'and enter them angularly. A tube d leads from a source of air suctionor exhaust to a port 39a in head 39. On opposite sides of arm 35 arearms 42 secured upon shaft 36 and having suitably curved cam-likeforward edges 42a adapted to coact with shaft 40, or with rollers 43thereon (Fig. 33), to cause required movements of arm 35 and head 39.Shaft 36 is to be rocked at a suitable time, for which purpose l haveshown said shaft provided with a toothed segment 44 in mesh with a rack45, suitably guided upon standard l and pivotally connected by a link 46with va rock arm 47, pivotally supported by frame 1 and connected by alink 48 with a crank 49 carried by shaft 27 (Fig. 6). When arm 35 is inthe position for application of a head a to a`can body said arm willbear against a stop 50 on standard 1a, as in full lines `in Fig. 31, andwhen said arm is vbrought to the can-head receiving position of arms 42causing arm 35 to be carried with arms 42, and when arm 35 rests againststop 51 head 39 will be in proper position beneath the can bodies. Afurther movement of arms 42 to the left in Fig. 31 will cause arm 35 tobe pushed upwardly to bring its head 39 in engagement with the lowermostcan head a; in the stack, by reason of the cam surface 42a in coactionwith shaft 40,'and thereupon suction through tube a? Will be caused byany suitable means to pneumatically retaln such can head on head orplate 39. rllhe racks w1ll then so operate that arms 42 will return tothe right in Fig. 31,I and spring 38 wlll cause arm 35 to descend andcarry withl 1t said lowermost head a, dragging it from be tween thespring acting ngers 33, whlch ywill thereupon snap under the lowermosthead aof the stack to retain the stack in the magazine, While permittingthe can-head upon plate 39 to move away wlth arm 35. Said arm with arms42 will continue to move to the right in Fig. v31 until arm 35 restsagainst stop 50, Ibringing head a in position/v y When the parts are insuch position (Fig. 31) the now opposing can receiver 7 will be movedwith can body toward the head a that is upon head 39,' and when saidhead has been entered in the can body, (substantially as shown in Fig.34), and retained by friction, suction through tube d will be cut off,and the can body with the head applied w1ll be withdrawn, the movementof the can body toward and from head 39 being effected as presentlydescribed. The foregoing operations occur with each head to be appliedupon a can body in succession.

After a head is applied upon a can bod the turret A will rotate to carrythe headed can to the position to have the flange :z2

' seamed on the body. In the example illus- `tra-ted in the accompanyingdrawings, thel arrangement is such that the turret will make two stopsfrom the position where the head is inserted in the can body to theposition where the flange a2 is seamed on the can body, as illustratedin Fig. 1. The devices for seaming heads on can bodies are shown indetail in Figs. 15 to 19, and comprise means to bear on and rotatearound the flanges' of the heads, and to be pressed thereon underpneumatic pressure in accordance with the shape of the can and its head.A

Spindle is supported on a bracket or the like 56 secured on frame 1, andis providedF with a suitable chuck 57, substantially conforming to theshape of the can head a and adapted to enter the recess thereof. Thechuck 57 is preferably detachably connected with spindle 55, as by meansof a screw 58 (Fig. 19).l At 59 are rollers suitably spaced apart aroundthe chuck 57 and pivotally supported upon arms 60 to move relativelytoward and from chuck 57. The arms 60are pivotally supported at 60a'upon a rotative head 61, that 1s mounted to rotate upon spindle 55, andwhich may be driven by a belt from `a suitable source of power, or inany other suitable manner. The arms 60 and thereby the rollers 59 aremaintained, during operation, pressed toward the can heads presentedthereto upon the corresponding receiver 7, and for such purpose I haveshown head 61 provided with cylinders 62 in which are located pistons 63operatively connected with the corresponding arms 60. For such purpose Ihave shown arms 60 provided with projections 60b receiving pins 64carried bythe respective pistons 63. The arms 60 also carry suitablerollers 65- adapted to bear upon a master form 66, that is slidable uponspindle 55, and around which master form the rollers 65 roll when head61 rotates. Means are provided to supply fluid pressure n inthecylinders during the operation of the seaming on the can heads tocause the rollers 59 to press on the flanges of the can heads.

I have shown the head 61provided with an annular channel 67communicating with the packing held in place by screws 71. The v packingmay be retained in place by a suitable nut or gland 71a (Fig. 15). Thechannel 67 may be provided lbetween the periphery of head 61 throughwhich the cylinders open, and a shell or ring 67 surrounding and fittingtightly thereon, and held in place by a nut or ring 67b on head 61,(Figs. 15 and 16). By removing shell or rin 67 access may be had to thecylinders an pistons. The chamber 69 may be supplied with compressed airthrough a channel 72 in spindle 55, the inner end or port 73 of saidchannel communicating with chamber 69, while the outer end of thechannel is connected by tubing 74 with a source of compressed airsupply. The passage 75 in spindle 55 may supply lubricating oil to thebearing of rotative member 61, as through a tube 76 from a suitablesource of supply. The master form 66 is preferably shaped substantiallyto conform to the sha e of the can body and its head, the shapeillustrated in the accompanying drawings being substantially oval. Bymeans of rods 77 slidable in bores in spindle 55, and suitably connectedwith master form 66, said master form may be slid back and forth alongspindle 55 by any suitable means, suitaby tuned to permit rollers 55 togradually approach the can head as the flange lthereof is reduced indiameter by the pressure of said rollers thereon. I have illustratedmeans in Fig. 1 for causing such movement of master 65 as will bepresently described. (The arrangement is such that whena can Ibody withits head applied (Fig. 34) is presented to the chuck 57 1t is pushedthereon a suitable distance, while the master 66 is substantially in theposition shown in Fig. 15, holding rollers 59 retracted. As the head 61with the pistons and rollers continually rotate, the master 66 will begradually pulled outwardly from under the rollers 65, therebypermittingthe air pressure against the pistons to force the rollers 59 against theflange of the can body for rolling the same down for seaming the flange,the continued outward movement of master 66 permitting the rollers 59 toact wn the flange a2 to the desired extent.

c. For this purpose all of the cylinders 62 communicate with the singlechannel 67, whereby the pressure in the cylinders will be equalized,while the pistons are caused to reciprocate by contact with the oval orother shaped flange of the can head during rotation of member 61.Suitable means, such as an automatically operating valve, may beprovided for causing pressure in channel 67 to be started just beforethe master form 66 is pulled to the right in Fig. 15, and to be relievedjust before master form 66 is pushed to the left in Fig. 15, to thenrelieve thc pressure of rollers 65 on said master, so that when themaster form is pushed to the left to cause withdrawal of rollers 59 tothe opened or spread position, the work of pushing the pistons outwardlyagainst air pressure will be reduced. The desired pressure may beadmitted to channel 67 just after a can body with its head a applied ispresented between rollers 59, and such pressure may be continued untilsaid rollers have acted sufficiently or as desired upon the flange ofsaid head. lin Fig. 1 the tube 74, which may communicate with thecorresponding channel 72 of both rotary v seaming heads, connects with asuitable airf controlling valve 78 receiving compressed air through pipe79 from a suitable source.

` A cam 80 (Figsfl and 6) on shaft 27 may operate an arm 81 forcontrolling valve 78 at the required time to admit air preure to andrelieve it from channels 67. Valve 78 may have a vent to relieve thepressure in channels 67. Valve 78 may be any wellrnown quick-actingvalve such as ordinarily used for. air or steam.

While `the desired action of rollers 59 upon a can-head flange may beutilized with a single rotary head 61 for seaming, it is preferable, insolne instances, toutilize two 'of such sets of devices, as illustratedin Fig.

1, the Iirst set (at the left in Fig. 1) for partially turning orseaming the flange and the second set for completing such seaming. Thetwo rotary heads may be substantially the same as described withrespect/to Figs. 15 to 19a, but will be so set with relation to eachother and to turret A that the rotary head 61 Vatthe right in Fig. 1,will` be in position to receive a partially seamed can body and head onthe next step of turret A after a body having a partially seamed headhas been withdrawn from the left hand rotary head 61 in said li re. Whenthe partially seamed flange o the can bod has been presented in righthand 'rotary ead 61, the pressure will be admitted in its channel 67 forcausing its plstons and rollers 59 to act with'the required pressure forfinally seaming Athe flange a2, the corresponding master 66 beingoperated in a manner before described. The masters 66 may beautomatically actuated, and said masters of both rotary heads may beoperated together by the following means: Rods 77 of the left hand head61 are secured to a block 82 (Fig. 1) that is connected with abell-crank lever 83 pivoted upon bracket 56 ;y a rod 84 pivotallyconnects lever 83 with a corresponding bell .crank lever 85, pivotallysupported upon bracket 56 with respect to the right hand rotary head 61,arm 86 connected with lever 85 being is connecte to the rods 77 of theright hand Vhead 61. A rod 88 is pivotally connected at one end withlever 85 and at the other' end said rod is provided with a guide yoke88EL having a pin 89 coacting secured upon shaft 24a journaled inbearings in frame 1 (Figs. 1 and 6). As cam 90 is rotated, the rods 77of the respective rotary heads 61 will be reciprocated at the "propertime for movin the respective mas` ter forms 66 back an forth withrespect to the corresponding rollers 65 of the respective pistons. Afterthe seaming has been finished upon the can head, by the devices of theright liand rotary head 61 (Fig. 1), the can body is withdrawn from saidhead and at the next step of turret A said can body is brought to aposition indicated at :a in Fig. 1, ready to be discharged or removedfrom the corresponding receiver7.

While any suitable means may be provided for rotating turret Astep bystep, and for causing the can body receivers 7 to be projected outwardlyand drawn in with can bodies thereon, I have illustrated means for suchpurpose as follows: Since turret A is illustrated as provided with eightcan body receivers 7, the plate 4 is shown provided with eight groovesor recesses 5 receiving the corresponding slides 6 (Fig. 21) and theGeneva wheel 2O is shown provided with eight correspondingly disposedgrooves 21 (Fig. 26), whereby the turret A will be given eight steps foreach complete rotation thereof. Since, in the example illustrated, thereare six points at which operations occur with respect to a can body,such as the application of a body to a receiver 7, the straightenin ofthe seam .of the canV body, at 30, the application of the head to thecan body adjacent to the magazine 32, the seaming of the flange of thecan body head a-t the two rotary heads 61, and the delivery point forthe headed can bodies at the point m, I provide means to cause thereceivers 7 to be moved outwardly and 1n- Wardly for each of'such sixpolnts, the other connected with a block 87 that with a cam two 4pointsat which the lreceivers 7 are brought 'by the rotation of Geneva wheel20 not requiring relative movement of the reh points I provide devicesas followsz'Beneath plate 4 and concentric with rotatively guided shaft2 is a plate 92 (Figs: 6, 20, 22 and 23). Plate 92 is shown providedwith six appropriately located radially disposedl slots or grooves 92",shown opening through the periphery of sald plate, adapted to slidablyreceive blocks 93. Said blocks are shown rovided with lianges 93", onopposite si es, bearing against lthe bottom of plate 92, which blockss'lidably rest upon a cam plate 94 that is rotatively supported beneathplate 92 and guided around shaft 2, (Figs. 6, 20, 22, and 23). Plate 92is shown provided with an annular groove or raceway 92" (Fig. 22) whichcommunicates w1th the slotsy or grooves 92". The lblocks 93 are providedwith transverse grooves 93", which open through the sides of saidblocks, which grooves 93" are adapted to coincide with the annulargroove or raceway 92" of plate 92,

vin certain positions of blocks 93 (Fig. 22).

Heads 95 are adapted to slide in groove 92", being shown provided withcurved surfaces for such purpose (Figs. 22 and 25), which heads areadapted to enter the grooves 93" of blocks 93 to Ibe moved therewithradially respecting plates 92 and 94 (Figs. 20, 22, 23, 24). Heads 95receive pins 96, shown adapted to t in openings 95 of said heads, andalso fitted in openings in slides 6, said pins being adapted to slide inradially disposed slots 4" in plate 4 (Figs. 20, 21 and 23). Since, inthe example illustrated, there are eight slides 6, there will be acorresponding pin 96 and head 95 for each slide 6, and since there aresix points at which operations occur with respect to the can bodies ofturret A, 'the six grooves 92" and six blocks 93 in such grooves willsuffice, although all of the eight heads 95 may operate in succession inthe grooves of corresponding blocks 93. When a head 95 is in the grooveof a block 93, the latter is tobe moved radially,`

and a corresponding slide 6 with its can body receiver 7 will becorrespondingly moved because of the interposed pin 96. Any suitablemeans may be provided for reciprocating blocks 93 in grooves 92"l ofplate 92 atthe proper times. For such purpose I have shown plate 94provided with cam grooves 94a positioned with respect to grooves orslots 92 of plate 92 and adapted to receive pins 97 that project fromblocks 93 (Figs. 22 and 23). By preference, rollers 98 are carried bypins 97 for engagement with the cam grooves 94a. Pins 97 may be retainedin position by nuts 99 seated in recesses 93c in blocks 93, (Figs. 20and 24).

The` arrangement described is such that when c'am plate 94 is rocked oroscillated, its grooves 94", by coactiomwith pins 97, will cause blocks93 to be reciprocated. When plate 4 is brought to rest a head 95,corresponding to a slide 6, is presented in the groove 93" of one of theblocks 93, and then cam plate 94 is given a to and fro movement,whereupon its cam Grooves 94a cause blocks 93 to move outwardly and theninwardly, carrying slides 6 and. receivers 7 therewith, terminating thestroke with heads 95 in register with groove 92" of plate 92. On thenext step of plate 4 the heads 95 pass through groove 92" until certainof said heads rest in the grooves 93" of the next adjacent blocks 93,whereupon cam plate 94 is again moved to and fro to cause certain slides6 to be again moved outwardly and inwardly, and so on each step of plate4 where slides 6 are to be given a to and fro movement. The foregoingpertains to six of the slides 6, whereas the heads 95 of two otherslides, not then to be reciprocated, as with respect to the points y andy2 (Fig. 1), will be 1n the appropriate parts of groove 92" of plate 92,and so on. The means I have shown for oscillating plate 94 are asfollows: At 100 is a cam secured upon shaft 24 above frame 1, (Figs. 6,27 and 35), and adapted to coact with a pin or roller 101 carried by arod or link 102, shown having a forked end 102a guided by shaft 24, theopposite end of said rod or link being pivotally connected With plate94, as by pin 103, which is shown adjustable in a slot 104 in plate 94(Fig. 27). When heads 95 havefbeen presented in grooves 93" of blocks93, and plate 4 has come to rest, cam 100 will, through link or rod 102,cause plate 94 to be rocked or reciprocated to and fro one stroke eachway, whereby the cam slots 94a will cause blocks 93 and slides 6 to bemoved in and out, terminating the stroke with heads 95 in register withgroove 92" of plate 92.

If no further operations are desired to be performed upon the can bodieswhile they are carried by turret A, after the bodies have been headedand seamed, the can bodies may be removed. In the example illustrated inthe accompanying drawings I have provided means for removing the headedcan bodies from turret A and supporting them upon a second or companionturret B that is spaced a suitable distance from turret A upon frame 1.Turret B may be made substantially in the same manner as turret A andprovided with a corresponding number of can body gripping or receivingdevices indicated generally at 7, which may be removably attached uponthe ends 6" of slides 6, as by clamping screws 14a in manner similar tothat described with respect to slides 6. Turret B may have plates 4 and16 receiving slides corresponding to slides 6 of turret A, togetherwith' the plates 92 and 94 and interposed blocks 93 and pins connectingsaidA parts, in manner described with respect to turret A, for causingthe gripping or receiving devices 7a to be projected and retracted asturret B rotates step by step. A Geneva movement, having a camwheel 20provided with slots 21L and an arm 22 having a pin or roller to coactwith said slots and carried by a shaft 24 supported by frame 1 may beoperated in timed relation to turret A throu h gearing 25, 26 andV shaft27 for causing step by step rotation of turret B simultaneously andcoincidently with respect to turret A, (Fig. 6). lin the exampleillustrated the can bodies having the heads seamed thereon, ashereinbefore described, are brought to rest successively upon a receiver7 of turret A, opposing a gripping or receiving device at 7a of turretB, and at suitably spaced distances around turret B means are providedfor beading the can bodies adjacent to.

their ends at b2 (Fig. 14) opposite their heads, at the position shownai; z Fig. 1, and for bumping or pressing the seams at the beads b2, asat the point e2 (Fig. 1), and for delivering the can bodies from turretB as at the point e (Fig. 1). Since, as illustrated, there are but fourpoints of operation with regard to the can bodies respecting .turret B,it will only be necessary to cause the gripping or receiving devices 7Lto be projected and retracted at each of such four points. Hence, asshown in Fig. 28, plate 92 is provided with four radial grooves 92f(correspondin to the grooves 92a, Fig. V22), and plate 94 as fourcorresponding cam slots 94t (corresponding to the cam slots 94 of plate94 Fig. 22). Flate 4 carrying the slides 6 that support the grippers orre ceivers 7, will be provided with eight slots and slides in the mannerillustrated and described with respect to Figs. 20 `and, 21, and thepins 97a from blocks 93 will work in the cam slots 94t similar to thecorresponding parts described with respect to turret A. The blocks 93have transverse grooves93 adapted to receive blocks 95 receiving pins 96(Figs. 28, 29, 30) from the corresponding slides 6, (in manner described with respect to similar parts in` Figs. 20 and 21). Plate 92 hasthe annular groove 92g communicating with the slots or grooves 92f forthe passage of the heads 95, (in manner similar to that before describedregarding turret A). Turret B is mounted upon'a shaft 2 connected withGeneva wheel 20a in manner similar to the connection of shaft 2 withGeneva wheel 20 of turret A. Cam plate 94 of turret B is to be rocked toand fro in unison with cam plate 94 of turret A, for which purpose a rod105 (Figs. 1, 6, 22 and 28) is pivotally connected to plate 94 at 106and with\plate 94 at 107,

lbody from receiver 7.

and `by, means of suitable pin and slot connection between said rodl andsaid plates adjustment may be made for accurate movement of one plate byanother. Such lpin and .slot connection may be similar to that shown inFig. 27a. By the means described the single cam 100 may be utilized foroscillating plates 94 and 94e in unison and to the same extent to assurethat the respective slides 6 and their opposing receivers 7 and 7a(Fig. 1) will all work together in proper timed relation.

The receivers 7a of turret B are provided' with means for gripping theheaded ends 0f the can bodies and removing said bodies from thereceivers 7 of turret A and retaining said bodies for operations thereonand discharge thereof from receivers 7. As shown in Figs. 1, 4 and 5 thereceivers 7a are provided with gripping fingers 108 pivotally carried byshafts at 109 on opposite sides of the receiver adapted to grip theheaded end of cans b therebetween. Springs 110 connect arms 111respectively secured to shafts 109 for normally drawing the fingers 108toward the can body. One of the shafts 109 of each receiver 7a isprovided with an arm 112 for causing discharge of the can bodies ashereinafter explained. The shafts 109 are connected by projections 113with a plunger 114 slidable in a bore in the corresponding receiver 7,and normally held retracted in line with the head of a can body when thelatter is held between the ngers 108. When arm 112 has operated fingers108 to release a can body the plunger 114 will be pushed forwardly tovdischarge a When a headed can body is brought to rest on a retractedreceiver 7 at the point :c (Fig. 1) a receiver 7EL will be retractedopposite said can body. When the plates 94 and 94 are next rocked tocause the corresponding slides 6, 6, to move outwardly, the receiver 7carrying the can body and the receiver 7a opposed thereto move towardeach other, andthe corresponding fingers 108 snap over the headed end ofsuch can body and then when plates 94 and 94e are again rocked reverselysaid receivers 7 and 7a are moved apart and the can body, `then held byfingers 108, is withdrawn from receiver 7 and retained upon receiver 7.On the next rotary step of turret B in the direction of the arrowthere0n.`(Fig. 1) said receiver is not projected outwardly, but on thenext step of turret B, said receiver, with the can body thereon, isprojected outwardly by the appropriate cam slot 94E to locate the openend of the can body in position to be beaded adjacent to said end, atthe position e (Fig. 1). Devices for beading can bodies are shown inFigs. 1, 6, 7, 12, 13, and` 14. At 115 is a head supported by a bracket116. carried by frame 1, in position opposite a can body whenbrought torest by turret B.
